Launched by AWS, the AWS Center for Quantum Networking (CQN) quantum network research center will focus on communications hardware, software, and applications.

Amazon Web Services is taking a step forward in an as yet unexplored area of ​​quantum computing: networking. The AWS Center for Quantum Networking (CQN) will seek to address the scientific and technical challenges of creating quantum networking hardware, software and applications, AWS said. The Center will expand on other quantum networking work led by AWS within the AWS Center for Quantum Computing, Amazon Quantum Solutions Lab and its Amazon Braket service. The latter offers a development environment to create quantum algorithms, test them on quantum circuit simulators, and run them on various quantum hardware, including Rigetti and D-Wave computers.

To exploit the full potential of quantum computers, it is necessary to connect them within a quantum network. Although they do not attract as much interest as quantum computers, quantum networks have fascinating potential applications, CQN researchers Denis Sukachev and Mihir Bhaskar said in a blog post. Distribution of quantum keys with levels of privacy and security unattainable with conventional encryption techniques, the researchers wrote. Quantum networks will also be able to deliver powerful and secure quantum servers in the cloud by connecting and amplifying the capabilities of individual quantum processors.

Limitations overcome

Quantum networks will use some technologies already implemented for modern optical communication, such as lasers, fibers and detectors. However, quantum networks rely on individual photons to transport the data and not on powerful lasers capable of transporting the data on channels of different wavelengths. This feature has drawbacks. While single photons provide many special capabilities for quantum networks, they also pose a major challenge because quantum mechanics prohibits their amplification, limiting the range of the network, the researchers wrote in this blog. In addition, the weakness of individual photons complicates their interface with current quantum computer devices. This means that it will be necessary to develop new special technologies, such as repeaters and quantum transducers, in order to implement global quantum networks, the researchers explained.

In addition to AWS, the quantum society continues to grow. It includes Cisco, Juniper, IBM, Intel, Microsoft, Google, Baidu, Honeywell and Quantinuum. For its part, Cisco announced the preparation of a hybrid networking environment capable of supporting classical signals and other technologies that use photonics to transmit server-to-server qubits. Cisco says that photonics, which uses light to transmit data and control various networking mechanisms, will also play an important role in most quantum environments. Some say the industry will not adopt quantum in a meaningful way for five to ten years, but the interest is certainly there. Gartner predicts that nearly 40% of large companies will have quantum initiatives in place by 2025, and IDC estimates that the global quantum computer market will be worth $ 16.4 billion by 2027. According to IDC, these investments will result in waves of innovation and technology breakthroughs. which will allow companies to use quantum computers for a diverse and ever-richer set of use cases involving analysis of huge datasets, an exponential number of variables, and an infinite number of possible outcomes.
